Possible Interaction: Hallucinogens and Marijuana

“Indeed, the possession of cannabis , 3,4-methylenedioxy-N-methylamphetamine (MDMA; also known as ecstasy) and psychedelics is stringently regulated.”

“Age and use of cannabis and hallucinogens were confounding variables.”

“Risk factors for hallucinogen use included male gender; use of alcohol, marijuana , or cocaine before age 21; and binge drinking.”

“In multivariable models, using marijuana “to experiment” decreased the odds for reporting use of hallucinogens other than LSD and narcotics other than heroin.”

“Using marijuana for “insight” increased the odds for use of hallucinogens other than LSD, and use due to “boredom” increased the odds for reporting use of powder cocaine and hallucinogens other than LSD.”

“Using marijuana to increase effects of other drugs increased odds of reporting use of each of the eight drugs, and using it to decrease other drug effects increased odds of reporting use of crack, hallucinogens other than LSD, and amphetamine/stimulants.”

“Conclusions Exposure to environmental influences associated with urban upbringing may increase vulnerability to the psychotomimetic effects of cannabis use later in life.”

“The aim of this … the use of marijuana … hallucinogens (e.g. LSD), with a specific focus on the idea that two separate mechanisms might link marijuana use to hallucinogen … nonusers; (2) increased probability of hallucinogen use for marijuana users versus nonusers, once the opportunity to use hallucinogens has occurred.”

“ Cannabis may trigger flashbacks after consuming hallucinogenes; the probability of the occurrence of a flashback seems to increase with the amount of hallucinogenes a person has consumed.”

“In persons who have previously taken hallucinogens, marihuana may also trigger recurrences of hallucinogenic effects and may occasionally precipitate delayed psychotic reactions.”

“Moreover, healthy subjects who frequently use cannabis , have a blunted psychotomimetic response.”
