In recent years, many ‘new’ drugs have arrived on the market. These are often advertised as ‘legal highs’, despite the fact that in many cases they are not legal. These substances are also marketed as ‘synthetic drugs’, ‘party pills’, ‘research chemicals’, or ‘plant food’, and are often used as substitutes for other illegal drugs. They are sometimes sold in stores or online and marketed as ‘legal’ and ‘safe’, however, many contain ingredients that are actually illegal and potentially very dangerous.
Taking these is like a roll of the dice — they haven't been around long enough to know what the immediate risks are or what might happen later on in life to people who use them. See the 'Emerging Drugs' factsheet for more information.
