You smoked in college, or you smoked last month, and you think that settles it. Here is the actual rule, the actual form question, and where you sit on the clock.
You smoked weed. Maybe a few times in college, maybe last month, and now there is a cleared job in front of you. So here is the question you typed: can I get a security clearance if I smoke weed, or if I used to? Usually yes. Here is the rule the government runs on, the exact question on the form, and what happens after you answer it.
Past marijuana use is relevant, but not determinative. Those are the words the Director of National Intelligence used in a December 2021 memo that agencies still work from. In plain English: it counts, and it does not decide.
Nobody gets an automatic no for smoking weed in college. Three things drive the answer. How recent it was. How often it happened. Whether it is over.
The myth I hear most. That any past drug use ends the conversation. It rarely does. Some agencies are fine with marijuana once it is more than a year behind you. Stricter ones want three years. It varies by agency, and every case gets read on its own.
The numbers behind the fear. One batch of 2,716 clearance denials, from October 2021 through July 2022, breaks down like this. Money caused 29.0% of them, the largest slice by far. Criminal conduct was 19.4%, personal conduct 16.4%, and drug involvement 11.1%. Drugs and alcohol together came to 19.8%, and both of those turn mostly on time. Most of the drug denials are not really about the drug. They come from hiding it.
The one hard line. Stop when you sign. That same 2021 memo tells agencies to advise applicants to refrain from any future marijuana use upon initiation of the national security vetting process. It then says exactly when that process starts: it commences once the individual signs the certification contained in the Standard Form 86. That signature is the date to circle. After it, use is a separate problem with no time behind it. The form also asks straight out whether you have ever used while holding a clearance.
Section 23 is the drug section. Most people have never read it, and it is smaller than they picture.
The preamble. Before the first question, the form makes a promise. Your answers here, and anything derived from them, will not be used as evidence against you in a subsequent criminal proceeding. Then it sets the ground rules. These questions cover illegal drug use in accordance with Federal laws, even though permissible under state laws.
The first question. In the last seven (7) years, have you illegally used any drugs or controlled substances? The form counts injecting, snorting, inhaling, swallowing, experimenting with or otherwise consuming. Weed gets its own box on the drug list: THC (Such as marijuana, weed, pot, hashish, etc.). An edible counts. One hit at a party counts.
What a single entry asks for. The drug type. The month and year of first use. The month and year of most recent use. The nature of use, how often, and how many times. Whether the use happened while you were a law enforcement officer or in a public safety job. Whether it happened while you held a clearance. And whether you intend to use in the future, with an explanation either way. Each date field has an Est. box beside it, so an estimate is built into the form rather than held against you.
The rest of the section. The other questions cover the last seven years of buying, growing, selling, shipping, or handling. They ask whether you have EVER been involved with drugs while holding a clearance, or while in law enforcement or another public safety role. They cover prescription misuse in the last seven years. And they ask about counseling or treatment, ever.
Use older than seven years. The drug question asks about seven years, so older use gets a no. No use inside seven years means the form answer is no. The only ever questions in this section are the ones about a clearance or a law enforcement job. An investigator can still ask whether you have ever used when you sit down together, and that question gets a plain answer too.
The form that is replacing it. The Personnel Vetting Questionnaire asks something narrower: whether you have used marijuana or a cannabis derivative in the last 90 days. It also asks about use in a national security or criminal justice job, ever, and about sale or growing over five years. The first of those forms were collected in the second quarter of fiscal 2026. Uptake started slow, and full use is targeted for September 2027. Today it is almost certainly still the seven-year question. The rest of the paperwork is its own project: how to fill out the SF-86 walks through it.
No waiting period is written into the rules. None. Four things get weighed instead: how recent the use was, how often it happened, whether you intend to use again, and how likely a repeat looks.
That is unsatisfying, so here are the numbers that do exist:
Use within the past few months of applying will almost always raise real concerns. Months are the tight window. Years are not.
What the clock is really for. It sets the order you apply in, not the ceiling. If your last use was recent, contractor work at the Secret level is where to start. The calendar keeps running while you are employed and cleared. The Intelligence Community is the strictest door, and it will still be there in two years. By then you can knock with a clearance already on your resume. Getting an employer to put you in for a clearance is the piece that decides everything else. How clearance sponsorship actually works covers the four routes.
The cutoffs also bend more than the web suggests. One applicant admitted marijuana use ten months before applying to a CIA internship, where the stated window is twelve months. He was invited to interview anyway, and told to show up and be specific. There is no clean cutoff line. Cases get read one at a time.

Stop thinking about this at the state level. It is federal, all the time.
Your state's law. It changes nothing here. The form says so in its own words. These questions follow federal law even where state law permits the use. A legal state, a legal age, and a receipt from a licensed shop all leave your answer exactly where it was.
A medical card. Also nothing. The CIA says it on its own hiring page: medical marijuana remains illegal under federal law. A card is a state document. A clearance is a federal decision. You list the use with dates, the same as anyone else.
CBD. This one catches careful people who were trying to stay clean. The 2018 farm bill pulled hemp out of the definition of marijuana, but only under 0.3 percent THC. Anything above that line is still marijuana under federal law, whatever the label claims. Here is the part nobody sees coming. The FDA does not certify THC levels in CBD products, so the percentage is never guaranteed. Products have tested above that line despite the label. A CBD gummy can produce a positive marijuana test. If that is you, say so and keep the receipt.
Weed stock. Put money directly into marijuana growers or retailers, knowing what they do, and it can be read as questionable judgment under the personal conduct part of the standard. Owning a sliver of the same company by accident is different. Inside a diversified mutual fund traded on a US exchange, the holding is presumed to be unknowing, and the memo says it should not be treated as relevant at all. Selling a direct holding counts in your favor.
What settles the concern. The drug section of the standard lists what raises a flag, and then lists what puts it back down. The second list is the one almost nobody reads. In plain words, it counts in your favor when:
That last item has a name: an attestation. The 2021 memo points to it as a way to show that future use is unlikely. Some agencies will ask you to sign one, so know that before the paper lands in front of you. The date on it is real, and so is the line about losing the clearance.
What goes in the box. Dates, not guesses. Work the calendar out before you open the form. First use, most recent use, and a count you can stand behind. Then the circumstances, in one or two plain lines. College. A party. A rough stretch after a breakup. Then the future-use question. If you have stopped, say no and give a short reason. Saying you intend to keep using is listed in the standard as a concern all by itself. That one sentence is doing more work than it looks like.
What happens next. Your yes does not set off an alarm. It starts a conversation.
The one rule in this section. Disclose it. In one published case, an applicant was denied over personal conduct for lying about marijuana use inside the seven-year window. He did it repeatedly. The smoking is not what sank him. Another listed no drug use at all, then admitted cocaine and weed during the interview, and the case was cancelled. The people who get cleared are not the people with clean histories. They are the people who wrote it down.
The polygraph. Only some jobs involve one, and most of those sit in the Intelligence Community. The lifestyle and full scope exams cover drug use. The counterintelligence exam does not. The question there is usually about the last twelve months, a much shorter window than the form's seven years. If the answer is no, say no, and leave it there unless the examiner asks for more. Who actually needs a polygraph has the rest of it.
Interim clearances. Whether you get one while the full case runs is a separate decision. The sponsoring agency makes it, reading your file as a whole. How long a security clearance takes covers how interims work and what the full wait looks like.
Short version: nothing, for you.
On 23 April 2026 the Acting Attorney General signed an order moving two narrow categories into Schedule III: FDA-approved products containing marijuana, and marijuana sold under a state medical license. A hearing on the bigger question, moving marijuana itself out of Schedule I, began on 29 June 2026. Recreational marijuana stayed in Schedule I.
Here is what did not move. The 2017 national security guidelines and the 2021 marijuana guidance were not changed. Use by someone who holds a clearance is still disqualifying, even where state law allows medical use. The lawyers who handle these appeals read the new rule the same way.
So the search that brought some of you here, security clearance marijuana schedule 3, has a boring answer. You are graded on the same rules as last year.
If weed is the reason you have not applied yet, cross it off the list. What decides this is not your history. It is whether an employer puts you in for a clearance in the first place. Money trouble, foreign family, and an old arrest are the other three fears I hear. What actually disqualifies you from a security clearance takes those one at a time.
