It's not clear to me how these would have absolutely any relationship at all.
In other words, you need to have a slightly adventurous personality.
Perhaps for someone who is undercover and needs to fit in, sure, but I don't think that predisposes a personality to take drugs in their own time. For both alcohol and drugs I doubt it has any relevance to most intelligence roles.
How.. mundane.

Think: DEA employee, vs. DEA criminal informant. The job of the DEA employee is not to infiltrate drug gangs. It's to organize and monitor the infiltration of drug gangs. The criminal informant wears the wire. The DEA employee sits in the black van outside, listening to the wire.
The most common position in the CIA is "analyst." The job of a CIA analyst is to sit there in a cubicle and read/listen to all the evidence gathered by agents (or spy satellites, or wiretaps, or whatever), gathering any "interesting" stuff into a report (with a further fan-in to "senior analysts" who map-reduce all those reports into "intelligence".) Unlike an operative, an analyst doesn't even get to speak with any agents — let alone head out into the field to recruit them.
gotta be able to hang out on both sides of the tracks, dig?
That was when they told him that his offer was rescinded for past use of marijuana. They said there were no exceptions to the rule, but it was the only reason he was denied.
Edit: marijuana use is now common enough that investigators will actually grill you and accuse you of lying if you say you've never used marijuana.

"GROSS: (Laughter) Right. So I thought this was really interesting. You had to get national security clearance for your job.
MASTROMONACO: Yeah.
GROSS: One of the questions you had to answer was a kind of detailed list of your drug use. And you'd smoked marijuana.
MASTROMONACO: Yes.
GROSS: You had to say how many times (laughter).
MASTROMONACO: Yes. That was...
GROSS: Yeah. So you handled it by saying unknown. How did you come to the conclusion that that would be your answer, an unknown number of times?
MASTROMONACO: Because - well, because I really feel strongly about not lying. And so when the FBI agent asked me for a number of times and she said, you know, 20? And I was like, no. She said, a hundred? I said, no. And then when she got up to 500, I was like, I'm not saying - I'm not giving you a number because who knows if they're going to go try and prove the number? So I just said, unknown. And apparently from her reaction, nobody had ever said that before.
GROSS: You write that you had to get randomly drug tested almost every month. Is that because you'd said unknown or does everybody have to do that?
MASTROMONACO: No. Most people get drug tested, like, once or twice that first year. But I was drug tested quite often because I was very forward-leaning about my drug use, very open-kimono, as we would say. And so, yeah, every - just about every month, you'd get an email that said, you know, you have 24 hours to show up for your test. And I would. And it was fine because I wasn't. So I had nothing to hide (laughter)."
So - financial stuff is their number 1 clearance issue I've heard. If you're deep in debt, or otherwise demonstrate poor control over your financial life.
Next up is being part of the LGBT community - if you're in the closet. I've heard they don't care about people being gay per se, just the secret aspect of it. Anecdotally, I had a govvie friend mention an FBI analyst who had a side hustle in gay porn. Totally OK.
Being open about drug use, as long as it's not the hard drugs, I could see someone getting a pass for.
The FBI/DEA has/had stricter rules on drug use likely because part of the job could entail dealing with drug seizures.
True -- can't handle your money why would you deserve to handle the gub'mnts?
But also people massively in debt will get desperate and take bribes. And bribes work.
He didn't get the job, not sure if that was why.
At some point they went cold on her, and then told her to reapply the following year (which she tried for a few years). She'll never know why it didn't work out.
I know at least one person who was not intimidated by the lie detectors, and were able to conceal things which might have been an issue.
It is useful to explain a bit about the bureaucracy here: the clearance process consists of the investigation and the adjudication. These are two separate steps and often performed by different agencies. The investigation is often performed by OPM, but DoD switched to doing their own, the FBI always has, and it's acceptable to use private contractors (usually retired insurance investigators) up to the S level in some agencies. The adjudication is much more often performed by someone directly in the issuing agency, and agencies publish their own manuals to which adjudicators work. Although the general grounds for denial of a clearance are in statute, the exact rules of what conduct amounts to what grounds (in other words, the real rules of adjudication) are contained in these manuals.

In the present context, see "Guideline H: Drug Involvement and Substance Abuse," page 17 ff.
It depends. At least, it did when I went for clearance a decade ago.
a) I think recency as well as frequency mattered.
b) You had to be willing to stop.
I don't know how much (a) is still a thing but it was definitely back then. The other thing is it depends on your sponsor and who you get stuck with during the process - some people are going to care way more than others.
