Death is hereditary
I can answer some my self but uhhm 420 or google is your best bet.
Ok Number 1. There have been cases when people have been hooked by smoking canabis, but that sometimes occoures when another drug is added like cocaine which can get you hooked.
2. It depends on how much you smoke, some little people can't tell the difference but it can be like when your drunk, speach is sluphed and slow, reactions are slow, you will also do random things which may occour attention to your self.
3. Its very hard to tell which is the fake stuff, but most dealers will keep the fake stuff out unless you have a very shadey dealer off a corner in a dark alley which will most likely have some fake herbs or things in it, most dealers which wont add this kind of thing will deal at a house, there is a hard location and you can crack down, while if its just off a corner of a street then its not a good location and the dealer can jump off his car and drive off.
4. I would learn more things about canabis, try reading 420's canabis thread, lots of infomation is included in it and all about the historey etc.
