Some people aren't capable of healthy romantic relationships and will cause and experience a lot of pain through trying to have them. Should we stop everyone from trying because some percentage will end up in abusive situations, or with broken hearts, or even dead? Risk alone doesn't make something bad, just risky. The question is if the potential rewards make the risks worthwhile, and the answer for LSD for many is clearly yes. Learning how to deal with risk is just part of life.
