No, marijuana does not contain “alien DNA” from outside our solar system. This claim is purely speculative and lacks scientific evidence. Marijuana, also known as cannabis, is a plant that is native to Earth and belongs to the Cannabis genus. Its genetic makeup is derived from terrestrial sources, and there is no scientific basis or credible research supporting the notion that it contains DNA from extraterrestrial origins. It’s important to critically evaluate and rely on scientific sources when assessing such claims.
