THC and other cannabiniods remain in the body for weeks and dissolve not only in the brain but in the liver, lungs, kidneys, testes and ovaries. THC and alcohol together have a greater effect than either by itself. Marijuana distorts information processing, while alcohol enhances the effects of a neurotransmitter called GABA, which binds to neurons and slows their rate of firing, producing a sedative effect. Marijuana also has mild analgesic properties. THC also can reduce nausea.
Vomiting is the body's natural way of purging toxic substances.
If the vomit message is suppressed by THC, dangerous amounts of alcohol can be ingested and absorbed. Thus alcohol poisoning could become a real threat in rare cases. Smoking marijuana can deliver 3 times more tar than smoking tobacco. Marijuana's irritating smoke dilates blood vessels, reddens the eyes, and inflames nasal tissues. Regular use can lead to bronchitis.
