To establish drug supply, what must the prosecution prove?

• A. The defendant's prior convictions
• B. The defendant knew or suspected they were involved with a controlled drug
• C. The defendant manufactured the drug
• D. The defendant had lawful authority

Answer: (B)

The main idea is the mental state required for drug supply offences: the prosecution must show the defendant knew or suspected they were involved in supplying a controlled drug. That knowledge or belief about the involvement in a supply is what makes the act illegal. Mere possession, or merely manufacturing, doesn’t by itself prove supply unless it’s tied to that awareness of supplying.

This is why prior convictions aren’t needed to prove the offence, and even if someone manufactured the drug, that can be a separate offence—but you still need the knowledge or suspicion of supplying to convict for supply. Having lawful authority would negate the illegal nature of the act, so it’s not itself a proof of the supply, but a potential defence if the authority justified the possession or handling.
