Gynecomastia, or the development of male breast tissue, can sometimes result from the continued use of certain medications. Some of the more common medications that may result in gynecomastia with prolonged use include certain heart medications, mood stabilizers, anti-ulcer drugs, hormone regulators, and some recreational drugs including marijuana, heroin, alcohol, and amphetamines.
These drugs can alter the amount of testosterone within the body, contributing to the growth of breast tissue. The good news is once the causative agent is identified and discontinued, gynecomastia typically resolves with time. Otherwise, you could consider some male plastic surgery options.
