How much are you taking?
Extreme caution should be used when measuring doses. Pipettes are often used to accurately measure a dose. GHB, when sold as a solution, varies in concentration, so it is very important to know how strong the solution is, however, there may still be inaccuracies. Always start with a very small dose.
Sensitivity to the effects may vary from person to person. If you buy or are given a pre-prepared solution of these drugs, the risks of accidentally taking too much is especially high. Taking an unmeasured dose of an unknown solution is very risky, even if it seems like a small amount. Measuring out doses millilitre by millilitre using a pipette, and starting with a small dose, reduces the risk.
Are you taking GHB or GBL on its own?
Never mix GHB or GBL with other drugs.
Just a small amount of alcohol combined with GBL can have strong negative effects. A high proportion of those who experience negative effects after taking GBL have also been drinking alcohol or using other sedative drugs.
Are you taking responsibility over the risks you face?
These drugs may be carried in quantities enough for several overdoses, so it may be safest to prepare in advance the quantity you wish to take in one session so that when intoxicated, you can only take up to an arranged limit.
Friends should always look out for each other – if someone is suffering negative effects, seek medical assistance immediately. If they cannot be roused, put them into the recovery position until you can get help.
