Psychoactive drugs like Marijuana and LSD alter consciousness by interacting with neurotransmitters in the brain, influencing how information is communicated across various brain systems. Marijuana creates a sense of relaxation, euphoria, and may lead to hallucinations in larger doses. LSD brings about intense visual hallucinations, emotional shifts, distortions in time and size, and synesthesia.
