My first 3 trips on LSD were fun, hilarious. Same with Mushrooms. But after that they were living nightmares. 8 hours of pure hell and paranoia.
Experienced users have told me not to take anything like LSD or Mushrooms if you are having a bad day or week. I use to smoke tons of marijuana. I stopped in October 2014. My last joint I was so paranoid I thought I would stop breathing. After that I said no more. Why would I purposely want to do that to myself?
If you naturally have anxiety and are prone to nervousness its not good to do any drugs. And if you take these drugs with evil minded people you will mostly likely amplify your anxiety/paranoia, that is, if you have any underlying paranoia or anxiety embedded in your personality. Not everyone has anxiety or paranoia when taking these drugs, including marijuana.
My friend who I use to take Mushrooms and LSD with complained about hearing voices for weeks after dropping or eating the last hit. He would hear multitudes of voices speaking in his head. Luckily now he is okay, seeing that he hasn't done these drugs for over 15 years.
As for me, I would never do LSD or Mushrooms again, pot maybe one joint a year, but any other drugs, sorry no thanks.
