well alot of them can be dangerous...the right ones can be very hard to find depending on what area you live in .....just like there are cough drops (succrets i think) that have dxm in them that people trip off of...but they aren't aroudn here at all. and it has to be certain brands AND types of both to actually trip off of. another thing......how come dxm has become so popular on this site? when i frist came (oct) i never saw anyone talking about it...but now everyone does.
