LSD is probably one of the worst drugs/hallucinogens you can take out there. LSD could damage a relationship between family and friends, it could cost you your life to fix your life, and you could eventually end up in jail and die a miserable, and lonely death. The consequences of LSD are just as bad as the consequences of any other drug, such as marijuana and cocaine.
If anyone offers you LSD, whether it's your friend or a random homeless man on the street, always say no. LSD will impact your life greatly, and if you are young and taking drugs, it will get you into a lot of trouble. If it's a friend that offers you the drug, they are not actually your friend, as real friends know MUCH better.
