When the amount makes it "dealing"

This charge is about how much you had, not what you were caught doing. Each state sets a weight — the "trafficable quantity". Go over it, and the law can assume you meant to sell or share the drugs, even with no other proof. From that point, it's on you to show it was only for personal use.

The whole idea in one picture

How the weight changes everything

Cross the line on weight and a possession case can turn into a supply case on the spot. Here's the shift, step by step — and where it lands on you to push back.

What "trafficable quantity" means

Every state sets a cut-off amount for each drug. Get caught with that much or more and you can be charged with "deemed supply" — treated as if you were selling, based on the weight alone.

The key idea

  • Each drug has a set weight that counts as "trafficable"
  • At or over it, the law can assume you meant to supply
  • You can be charged with no cash, scales or messages

Rough thresholds (they vary by state)

  • Cannabis — around 250–300g
  • MDMA — under 1g
  • Heroin, cocaine or meth — around 2–3g

Exact cut-offs differ by state — see your state's figures further down.

How a charge usually starts

Drugs are found on you, in your car or in your home — and the amount is at or over the line. From there, the quantity alone can carry the charge. Police may also point to:

What backs it up

  • Residue on scales or bags
  • Large amounts of cash
  • Text messages or app chats

But here's the catch

  • None of that extra evidence is needed
  • The weight on its own can be enough
  • The charge is more serious than simple possession
The big difference: normally the police have to prove their whole case. Here, once you're over the line, the law assumes supply — and it's on you to prove the drugs were only for personal use.

What happens at court

Less serious matters can stay in the local or magistrates' court; bigger ones go to a higher court. The case usually comes down to three questions:

  1. Were the drugs in your possession — yours, and under your control?
  2. Was the amount over the trafficable limit?
  3. Did you intend to supply — or can you show the assumption is wrong?

Treated as "deemed supply". This is the maximum; actual sentences depend heavily on the drug, the amount and the circumstances.

Read this as a ceiling, not a forecast. Maximum sentences are rarely handed down. What actually happens turns on the drug, the quantity, your history and whether the supply assumption can be challenged.

Common defences

Because the charge rests on an assumption, a lot of the work is about challenging it. Common arguments include:

It was for personal use

The drugs were all for you, not for selling or sharing.

It wasn't in your possession

They weren't yours, or were outside your control.

The search was unlawful

Police gathered the evidence without the power to.

The weight is wrong

The actual amount is below the trafficable cut-off.
