Best realistic drug addons on Garry's mod

What's up guys, i was wondering if y'all got any ideas on which is the best realistic drug addon on Garry's mod?
Feel free to post your opinions too, i'm just interested and collecting opinions, if you can also drop me the gmodstore links too, i'll appreciate :]
Thank you !

Ohhh.. well, it's basically just an addon, there are no such "Realistic" ones ) By the way, a very strange question
