I spent a few hours browsing it last week and some of the memes there made me chuckle.
The dph subreddit honestly has some top tier humor
There was a post there that described it as LSD but scary. Sounds like a recipe for some wild memes to me
All the hard drug subs are interesting to sort from the top. You get memes with dark humor, deep insight of what a day with crippling addiction looks like, a couple heart warming stories about how someone is done with the drug for good and goes into rehab (never look into their profile to get a follow up) and in the case of r/meth you also get plenty of titties.
