Once sold at health stores, GHB’s effects are related to dose. Effects range from mild relaxation to coma or death. GHB is often used as a date-rape because it is tasteless, colourless and acts as a powerful sedative.
GHB is generally swallowed, although a small number of people inject it. It can be very hard to judge the amount taken, as the quality and strength of drugs can vary greatly from one batch to another.
Using GHB carries a high risk of overdose due to the small difference between the amount required to produce a ‘high’ and that which causes overdose.
Low to moderate doses
- feelings of euphoria
- increased sex drive
- lowered inhibitions
- memory lapses
- low body temperature
- slow heart rate
- low blood pressure
- muscle tremors
- urinary incontinence.
A high dose of GHB can cause a person to overdose. This means that a person has taken more GHB than their body can cope with. The effects can include:
- loss of coordination
- irregular or shallow breathing
- confusion, irritation and agitation
- blackouts and memory lapses
- unconsciousness (where people can’t be roused) that can last for 3–4 hours
- respiratory arrest (stopping breathing) and death.
