I don't intend to strike fear into people's minds but does anyone worry about the possible impurities in the commercial marijuana we all see? I've been reading Why Marijuana should be legal by Ed Rosenthal and Steve Kubby and some of the techniques that they have mentioned that people in Mexico do to make the brickwood and all the nasty schwag moist that comes from Mexico. Everything from pouring coca cola to animal feces just to moisten it. I know the thought would be to just avoid schwag and all the nasty pot that comes from Mexico which I'm sure most of you are able to do since you all get from pretty good bud to crazy bud. I, however live in Oklahoma where I think some of the worst nugget comes from in not only the United States but probably the world. Even though I've seen some very good schwag from around the country in Oklahoma we get mostly the awful schwaggy schwag that probably does come from Mexico along with mid-grade bud. I avoid the schwag and try to get the best I can and there have been times when I've been able to find dank nugget here it's just hard. But I have digressed quite a bit. Anyway, many times I've gotten and seen alot of almost nug-schwag looking pot that looked kind of moldy too. I guess the question would be do any of you worry about possibly smoking bud that is moldy and may contain bacteria from the mold or bud that may contain insect eggs from bugs gnawing at it? Or do you worry that pesticides were used by the grower of your marijuana? I know the worry isn't there if grown inside but you never know if it was grown indoors or outdoors and there are plenty of growers who don't care where it goes they just want money and they'll use pesticides because they would rather their plants not be eaten away by bugs and still not caring about the person who smokes it and ingests pesticides. I don't mean to scare anyone but this book makes me nervous even to smoke because of the impurities. I don't really know much about it so if anyone has any ideas I would appreciate your input and sorry for the long post.
