Do drugs give you a different perspective on life? Yes. That's what recreational drugs are used for. Temporary altered states. You won't stay messed up, unless you do. -laughs- And if you do, you were gonna end up that way anyway so don't worry about it.

My mom quit smoking weed regularly because she started getting anxiety whenever she'd get high. Maybe you're just having anxiety?

Oh, and to answer the questions of yours that I remember: Smoking out of some stuff is bad. Tin foil for example. Weed makes alot of people feel more creative. You probably aren't experiencing brand new emotions as much as amplified old ones. Alot of people have a hard time remembering stuff when they're on drugs, and what happened while on drugs, after the event. You will grow out of being so overwhelmed by weed as you smoke more times. And yes, it sounds like paranoia that you're amplifying and getting worried about. Get less stoned.
