Problems with people and drugs?

Hey man, experimenting can be fun, and obviously also very dangerous. I would say that it is completely up to you and your GF to make the decision to get into higher things (pun intended). I wouldn't do anything unless you know for a fact that both you and her will be able to cut it at anytime. Also, I've known couples that got completely lost in the land of experimentation, and ended up having nothing together, except drugs. They completely ruined their relationship. Also this might sound gay, but being sober if your not used to it with your girl can be a high in itself, by experimenting with different activities and such. You'd be amazed at what a seriously intense natural high can be compared to. Good luck man, and keep you and your girl safe.
