Picture of pills


(benzos, vallies, blues, Valium, Xanax, xannies)

Benzos are a type of depressant drug that are used in the treatment of anxiety and insomnia. Recreationally, they are usually used for their mood-lifting effects. Although benzos are prescription drugs, there is a huge amount of illicit production. This means that contaminated, incorrectly dosed pills have flooded the market. The most commonly used benzos are Valium (diazepam) and Xanax (alprazolam).

Effects | Dosage | Advice | Support


There are lots of different benzodiazepines available on the market. The effects of each are largely similar but vary in duration and strength.

Paradoxical symptoms (the opposite effects of those that are desirable) sometimes occur when a benzo wears off. This is more likely to happen with short acting benzos.


As always, dosage will depend on a number of factors including weight, gender and tolerance, amongst others. The following advice is a guide only. If the benzodiazepine you are using is not listed here you can click here for a dose conversion tool.
