Identify the groups of cannabinoids.

Cannabinoids are a class of diverse chemical compounds that interact with cannabinoid receptors present principally in the brain.

Natural cannabinoids are obtained from the inflorescences of the plant Cannabis sativa. The flower tops, leaves, and the resin of the cannabis plant are used in various combinations to produce marijuana, hashish, charas, and ganja.

Heroin, morphine, and di-acetyl morphine are opioids. Cocaine is a stimulant alkaloid obtained from the coca plant. LSD is a hallucinogen.

Therefore, the group consisting entirely of cannabinoids is Marijuana, Hashish, and Charas.

Answer: Marijuana, Hashish, Charas
