Hi Aaron,
Because meth is considered a Schedule 1 "hard drug", were you charged with possession under section 9 of the Drugs Misuse Act 1986 (Qld) or another offence?
If you were charged under the Drugs Misuse Act 1986 (Qld), you should consider engaging a criminal defence lawyer at your earliest opportunity.
If you don't have the means to pay for a lawyer, you may considering
contacting Legal Aid Queensland (1300 65 11 88 or 07 3238 3444), the
Caxton Legal Centre in South Brisbane or another member of the
Queensland Association of Independent Legal Services (QAILS) at your earliest opportunity to better understand the potential penalties involved.
Please keep us updated as to your progress.
