What proof do you have that your anxiety and paranoia are caused by your teenage LSD intake? There are plenty of people who have issues with anxiety and paranoia that have never taken drugs.
Consider that 70-90% of schizophrenics are tobacco users, and most started young. This is an astounding rate of smoking for a population subgroup. Did tobacco use cause the schizophrenia or did schizophrenics seek out tobacco?
Plenty of cults operate without drugging their members with LSD, if it was effective I assume it would be more widespread considering mental, sexual, and physical abuse are illegal and used as tools by cult leaders to maintain the cult and its membership. See NXIVM for a recent example. Giving people LSD is far more benign than beating or raping them.
