Tadalista CT 20 mg, which contains tadalafil, is a medication used to treat erectile dysfunction (ED). It is not classified as an addictive substance, and there is no evidence to suggest that it causes chemical dependency in the way substances like opioids or nicotine do. However, psychological dependence can occur in some users. This means that individuals may come to rely on the medication for sexual performance, particularly if they experience anxiety about their ability to perform without it. Long-term use should be monitored by a healthcare provider, especially to address any underlying psychological or physiological issues contributing to ED.
