marihuana/mar·i·hua·na/ (mar″ĭ-hwah´nah) marijuana.
tetrahydrocannabinol (THC), the most active ingredient of marijuana, can, with heavy smoking, narrow the bronchi and bronchioles and produce inflammation of the mucous membranes. In addition, marijuana smoke contains many of the same chemicals and “tars” as tobacco smoke and, therefore, increases the risk of lung cancer. There is some evidence that marijuana increases the risk for miscarriage and birth defects. Even though these dangers have not been completely documented, it is recommended that both men and women who plan to have children should avoid marijuana as they would any other unnecessary drug.
One beneficial effect of THC is the lowering of intraocular pressure, which can be helpful in the control of glaucoma. However, because it causes tachycardia and increased work for the heart, it cannot be used in most elderly persons, the age group in which glaucoma is most prevalent. Another use of THC is for relief of extreme nausea and vomiting in patients undergoing cancer chemotherapy, although not every patient responds favorably to THC.
