High Alert is warning the public to be extremely cautious after reports surfaced of a potentially toxic substance being misrepresented as 1,4-Butanediol (1,4-BD), particularly in Christchurch.

1,4-BD is widely used in industrial settings as a solvent and as an intermediate in the production of various chemicals and materials.

Beyond its industrial uses, 1,4-BD has been misused recreationally due to its conversion into gamma-hydroxybutyrate (GHB) in the body.

GHB is a central nervous system depressant known for its euphoric and sedative effects. Consequently, ingestion of 1,4-BD can lead extremely dangerous side-effects.

The organisation, which monitors drug-related risks in New Zealand, said it was investigating claims that what was presumed to be 1,4-BD could in fact be a dangerous chemical such as antifreeze.

While inquiries continue, High Alert said anyone considering using 1,4-BD or similar G-type substances should exercise extreme caution.

Drug checking is strongly recommended to reduce harm and detect adulteration.

“Misrepresentation can occur anywhere along the supply chain,” High Alert said.

People are being urged to use official drug checking services to ensure what they’ve obtained is what it claims to be. A list of upcoming clinics can be found on The Level’s website: thelevel.org.nz/drug-checking-clinics.

“If you or someone you know takes a G-type substance and starts to feel unusual effects, get to a hospital or call 111 immediately,” the organisation said.

“Be honest about what’s been taken and that it could have been adulterated. You won’t get in trouble, and it could save your life.”
