Gak

Australian slang term used to refer to street Amphetamine Sulphate, aka 'Speed'.

Once a popular street drug in Australia during the 80's, it's use began to decline during the 90's when powdered Methamphetamine began to surface, which was often sold to users as 'Speed' which it is not.

It's use and availability as a street drug is now uncommon, and has virtually been replaced by the more potent and more harmful drug Crystal Meth, which is known in Australia as 'Gear' or 'Ice'.

Amphetamine Sulphate (Gak) never had the high abuse and addiction rate or caused as many problems as Methamphatamine (Ice) in Australia, when it was around. I have personally heard this from police officers, drug councillors and former users who were around during the 80's.

Gak is also commonly known in Australia as 'Whipper, Whip, Speed, Whizz' or 'GOey
"Back in the day, you could get a bag of Gak, go out on the weekend, have a great time and it was all cool. Didn't fuck as many people up and turn them into tweakers like Meth does now days"

"GAK?! Fuck yea us rack up a line!!"
