There's a very fine line between the amount of GHB required to get someone intoxicated and how much will put them in a coma. As there's no way of knowing the strength of the GHB, the chances of overdosing are very high. Combining GHB with other drugs also increases the dangers. For example, using it with other central nervous system depressants - such as alcohol, valium or heroin – increases the risk of overdosing significantly.
