Just proves what I already said earlier in these type of threads. Legalizing does nothing to stop the illegal drug trade. Governments will set limits on drug potency and people will find ways to make more extreme versions.
All legalizing any of these drugs do is make it more likely others will try them and get hooked. The the cycle of needing more for the same high, then repeat the vicious cycle.
You wan to rethink that sentence?
