I knew they denatured it but not with this in mind. My grandfather was a state certificated chemist then and used to test what the police found I found his book and all they had were the percentages of alcohol not the impurities in it. Most street drugs are the same way who the fuck knows whats it them pot is probably the safest but you still have to deal with some shady people to get it. Legalization of it would be a good idea
