First of all this isn't an anti-weed post, I use weed regularly and enjoy it. What I'm arguing against is occasional use, once a month or less, at that level your tolerance usually resets between uses. The thing they don't tell you in health class is tolerance goes both ways, you become tolerant to both the positives and negatives of use. For weed the negative im referring to is anxiety, though short term memory loss also goes down with more regular use. Whenever I take a break and then start doing weed again I get way too in my head and anxious which usually goes away after a couple sessions. This has also become worse with modern legal strains that have become way too concentrated. Dispensary edibles are a bit better since you can dose them easier but even then the longer the time in between uses the more likely you'll forget what's a good dosage. I see this a lot with friends who don't regularly do weed and they smoke with me, get way too high, have a bad time and then won't do it again for a while and repeat the cycle. So for those type of people I'd recommend not doing weed at all or doing it more regularly so you can keep your tolerance up. No shame in picking either but the middle ground kinda sucks.

EDIT: a lot of people are saying get lower percentage strains or higher CBD ones, to that I'd say I wish I could. I always try and get the lowest percentage stuff I can find at the dispensary and that stuffs still usually in the high teens percent THC with less then a percent CBD here in SF. So I guess part of this is just a rant on how stupidly concentrated modern weed is and how it leaves little margin for error.
