I love weed on my own, however after tripping acid and rolling alone a few times I've found great pleasure in those, too. Only difference is I can smoke way more often than I can trip or roll. So...for a special occasion and when nothing else is going on, I'll take something else I have on hand just to see what it's like alone.
I think it goes way too deep for me to be around more than at most, one other person.
We did a 4 person group on 2C-E one time and it was a lot of fun until about 5 hours in, when everyone closed up inside of themselves and we all got paranoid that we were thinking bad things about each other.
none. i like doing drugs with other people so then you can talk about how amazing it is. but if i had to do one by myself i would smoke marijuana.
let me see this
Marijuana & Hashish - not as fun you wouldnt be able to laugh with your friends
Alcohol - thats kind of pathetic alcohol is like the most social drug ever
Stimulants - only one i've tried is adderall
Benzodiazepines (Valium, Xanax) - its like alcoholish but i havent tried it
Opiates - I guess that wouldnt be too bad those are good wherever your at
Hallucinogens - I might get scared and freak out
Research Chemicals - I dont know what that is really
Ketamine, DXM - i dont know i've only tried a little of dxm
I lie I lie, I've been using it to escape recently, not the most suitable drug for that I know.
Really, the best drug to go solo with is K. Nothing quite like feeling your very existence melting away from you whilst lying in bed. I find that if I take a high dose of K around other people they tend to fuck with me. One time my buddy shoved a cheerio up my nose whilst I was in a far away place. This is also quite dangerous though.. the whole risk of aspirating on vomit if you overdo it etc.
