Used in the over the counter medicine Benadryl
. I DO NOT recommend using this shit to get high. You'll see things you could swear are real. You'll cross over to the other side. You'll see spiders that aren't there. You'll have conversation with people that aren't real. You'll be freaked out of your mind by shit that humans aren't meant to see.
Take crack, take heroin, take acid, but don't do Diphenhydramine unless you want to get freaked the fuck out.
