Legal High Addiction | Types, Symptoms & Effects
A legal high drug, often referred to as a ‘new psychoactive substance’ (NPS), is a substance created to mimic the effects of illegal recreational drugs while avoiding classification as illegal. These substances are designed to be chemically different enough from banned drugs to skirt existing drug laws, although they still aim to provide similar psychoactive effects.
Legal highs can come in various forms, such as pills, powders or herbal mixtures and are often marketed under innocuous names like ‘bath salts’ or ‘spice.’ While they may not be illegal at the time of their creation, many of these substances can be dangerous, leading to health risks and potential addiction. Governments frequently update their drug laws to include these new substances, making them illegal as their risks become apparent.
