Recreational drugs pose several toxicological risks, including acute toxicity, chronic health effects, and potential for addiction. Acute toxicity can lead to overdose, characterized by symptoms such as respiratory depression, cardiovascular distress, and even death. Chronic use can result in long-term health issues, including liver damage from alcohol, lung cancer from smoking, and cognitive impairments from prolonged cannabis use. Additionally, many recreational drugs have a high potential for addiction, causing significant physical and psychological dependence.
