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 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 essential to critically evaluate such claims and rely on scientific sources for accurate information.
