LSD is usally liquid in form. Users then ingest the drug.
Some users experience a psychosomatic addiction, but that is purely psychological.
Besides that, users do not experience cravings as they may for nicotine, cocaine, or heroin. Ingesting LSD results in an 8 to 10 hour trip depending on the amount ingested. Users experience everything in a new way. All five senses are enhanced tremendously. Users may 'see' music and 'hear' colors.
