Charged with a Cannabis Offence in Western Australia?
Cannabis offences in Western Australia range from minor possession matters to serious cultivation and supply charges, and the consequences can vary significantly depending on the amount involved and the nature of the conduct alleged. While WA has a Simple Cannabis Offence Notice (SCON) scheme for very small quantities, any cannabis-related charge should be taken seriously. At Kate King Legal, our experienced Perth drug lawyers are ready to advise and represent you across the full spectrum of cannabis-related offences.
Types of Cannabis Offences Under WA Law
Cannabis offences in Western Australia are primarily governed by the Misuse of Drugs Act 1981 (WA). Depending on the quantity and the alleged conduct, you may be charged with one or more of the following:
- Possession of Cannabis (s.6 Misuse of Drugs Act 1981)
- Possession of Cannabis with Intent to Supply (s.6(1)(a) Misuse of Drugs Act 1981)
- Cultivation of Cannabis Plants (s.7A Misuse of Drugs Act 1981)
- Supply or Sale of Cannabis (s.6 Misuse of Drugs Act 1981)
- Possession of Cannabis Paraphernalia (s.9 Misuse of Drugs Act 1981)
- Simple Cannabis Offence Notice (SCON) — minor possession matters
The charge you face will depend on the quantity of cannabis involved, whether there is evidence of intent to supply, and whether cultivation equipment was found. Our lawyers will advise you on your options clearly from the first contact.
What Penalties Could You Face?
For small personal use quantities, police may issue a Simple Cannabis Offence Notice (SCON) rather than a criminal charge, which can typically be dealt with by paying a fine or attending a drug education session. However, where the quantity exceeds personal use thresholds, or where supply, cultivation, or trafficking is alleged, the criminal law applies, and penalties can be substantial, including lengthy imprisonment for supply-related offences, and significant penalties for cultivation depending on the number of plants involved. At Kate King Legal, our lawyers will assess the specific circumstances of your matter and work to achieve the best possible outcome.
Your Defence Options
Cannabis charges can be contested on a number of grounds, depending on the circumstances. Defences may include challenging the lawfulness of the search that produced the cannabis, disputing knowledge of the cannabis, establishing that any cannabis was for personal use rather than supply, or challenging the reliability of the forensic analysis. Where a SCON has been issued, we can also advise on whether election to court is in your best interests. At Kate King Legal, we take a strategic, evidence-led approach to every cannabis matter.
