But how do you know that's all that's in it? To my knowledge you don't need a license to make these chemicals or to sell them?
What's stopping me from setting up my own store and under cutting the competition with some cheap, low grade chemical imported from China?
As this market is so under regulated there could be any old shit in there. Let's face it, would you by medication from a car boot sale or down the local indoor market, I know I wouldn't.
