Final answer:
Studies consistently report that smoked marijuana and oral THC lead to an increased total daily food intake. Long-term effects of marijuana include brain development problems, coughing, and breathing issues, among other health risks.
Step-by-step explanation:
A multitude of studies have shown that smoked marijuana and oral THC increase total daily food intake. This effect is often referred to as the 'munchies,' which is an increase in appetite that can occur after marijuana use. While short-term effects of marijuana include altered senses and changes in mood, long-term use can lead to several issues, including problems with brain development particularly in those who begin using marijuana as teenagers, as well as potential coughing and breathing problems for those who smoke marijuana frequently. Some cannabinoid-containing drugs are approved to treat nausea from chemotherapy and to improve appetite in severe weight loss cases, like in AIDS patients. However, marijuana smoking also parallels many nicotine smoking risks, such as promoting cancer and cardiovascular issues, yet regarding the options provided, increased appetite is the effect consistently reported.
