Answer to Question 1
Answer: Because marijuana is usually smoked, users can end up with many of the long-term problems that tobacco smokers do. Problems may be heightened because pot smokers inhale deeply and hold the smoke in their lungs. Long-term health risks include daily cough and phlegm production, bronchitis and other respiratory problems, lung damage, impaired immune system functioning, impaired cognitive functioning, and possibly increased risk of cancer of the respiratory tract and lungs.
Answer to Question 2
Answer:
Ingestion is the process of swallowing and absorbing a drug through the digestive system. It is the slowest way for a chemical to reach the brain.
Injection is the process of using a syringe to inject a drug into the skin (subcutaneous injection), muscle (intramuscular injection), or bloodstream (intravenous injection), Injecting a drug into a vein sends it more quickly to the brain. As a result, the drug can deliver a quicker rush, but the high can also fade faster, which leads to repeated use and a higher addictive potential. Injecting a drug can expose a user to diseases.
Inhalation is the process of breathing a drug into the lung through the mouth or nostril. Like injection, it increases a drug's addictive potential because it speeds drugs into the bloodstream.
Mucosal absorption is the absorption of a drug through the mucous membranes. Chewing tobacco is absorbed through the mucous membranes of the mouth. Cocaine that has been snorted is absorbed through the mucous membranes of the nose.
Topical administration is typified by applying a drug directly to a body surface like the skin. A nicotine patch, which is applied directly to the skin's surface, is an example of topical administration.
