No. Standardization, rigorous testing, and FDA approval are good things.
But that's what we aren't getting with existing substances, instead what gets tested, standardized and approved are substances that are patented and immensely profitable.
I would love to see a future where I can get a government-standardized tab of acid. Of course this will never happen. The reason they are investigating how to get the 'good' effects without the 'bad/uncontrollable' effects is because of who is deciding what 'good' and 'bad' are. 'Good' = Allows people to continue functioning at a high level with the current power structures in place. Put in other words, it is only worthwhile to cure someone's depression if you can do it without the cure involving that person realizing that their current government isn't working for them.
I seriously doubt there's a drug that reliably makes your political opinions more correct and truthful, but I'm sure that there are drugs that impair your judgment so much that you cannot tell you are impaired. So I would suspect that LSD falls into the latter category, not the former.
If the changes are irreversible, I certainly wouldn't want to take that risk.
