<human>: Can you succinctly summarize the text in 1-3 sentences?

My bf is really into recreational drugs. Not necessarily doing them, he just researches them a lot, he subscribes to many drug-related subreddits, and he constantly mentions wanting to try some that are frankly really concerning. After listening to him talk about it, if it's genuinely concerning just from the sound of it, I'll say "maybe it's something you should wait to do," or "I don't know if that's a good idea." Most of the time, he'll tell me that I "don't understand," or "no, it's totally okay, I just want to try it once." So far the only drugs he's actually done are marijuana and LSD, and while I'm okay with the latter and we've come to agreements on using it, I think he's made a lot of progress since he took a break from smoking weed and it sucks that he doesn't see it that way. We've been dating for a while (over a year) and we have a lot of big plans for the future; I just don't want an interest in something illegal to ruin things for us. I understand that not all drugs are illegal, and that the recreational use of weed is slowly becoming legal, but it's a risk I'd rather he not take. 

If anything about this is unclear, please let me know.
<bot>: my bf is super into recreational drugs and I don't want it to be a big thing as our relationship continues.
