A survey of UK-based internet retailers found 1,308 products marketed as "legal highs," averaging £9.69. Most were pills (46.6%), smoking material (29.7%), or plant extracts (18.1%), and claimed to be stimulants (41.7%), sedatives (32.3%), or hallucinogens (12.9%). Safety information was severely lacking: 40.1% failed to list ingredients, 91.9% omitted side effects, 81.9% gave no contraindications, and 86.3% no drug interactions. The most common products included Salvia divinorum, Kratom, Hawaiian Baby Woodrose Seeds, Fly Agaric, and Genie. The authors conclude that uninformed users risk serious adverse effects.
