Tests have shown THC has mild-to-moderate pain-killing (analgesic) effects, and can be used for the treatment of pain. THC alters neurotransmitter release in the spinal cord, resulting in pain relief.
The compound is also known to stimulate appetite (informally known as “the munchies”) and induce a relaxed state, as well as other effects on sense of smell, hearing, and eyesight. THC can also cause fatigue. In some people, THC may reduce aggression.
Some studies have demonstrated that THC shows some promise for the treatment of nausea and vomiting – it may have antiemetic qualities that make it helpful for people undergoing chemotherapy or other treatment where nausea can be a side effect.
Medical marijuana is used to treat chronic pain, muscle spasticity, anorexia, nausea, and sleep disturbances. Medical marijuana is not subject to governmental standardization, making its ingredients and potency unknown.
Marijuana can be smoked, inhaled through vapor, brewed as a tea, applied as a balm, or eaten in products such as brownies or chocolate bars.
