Yeah that's pretty much what I was told by my two friends. They said it was definitely somethin your body gets used to but is fun your first few times or just once in a while. Either way I don't plan on smoking them that often except for after smokin a blunt and only when someone else has one cause I'd never buy one on my own..

Now that you mention it the head rush was similar to that of chewing tobacco. When I packed my first lip I definitely felt uneasy and light-headed so I can see the relation.
