My advice would be to be very careful. Yes, weed isn’t like cocaine, heroine, etc. But some people will lace marijuana with stuff like that and it can be very dangerous. If you are going to try it, try it with someone you trust and get it from someone you trust.
If you are going to try it, I would say have a drink near by just in case you cough a lot. Avoid going out in public because when i used to do it it used to make me very very paranoid and I hated it. Stay in, listen to music, watch something fun, talk to your friends and eat and relax.
