Understanding the risks of buying potentially adulterated or counterfeit products is another thing entirely, which would be helped greatly by increased commodification and legalization.
I myself have had bad / hell like experiences a small percentage of the time, despite literal hundreds of good experiences prior.
Becoming a father many years ago significantly altered my trip experience.
Dosage also plays a strong role..
These things are generally less toxic than alcohol and it is criminal to punish someone for having them or using them.. But they are also extremely powerful, and despite potential amazing experiences, do carry risks.
And they are definitely not for everyone.
