Notes

- The offence does not apply to a substance taken under a lawful prescription, but it does apply if the substance was not taken in accordance with the prescription.
- Section 117 sets a fine as the base penalty. The consolidated Act of 26 November 2024 was read; disqualification rules (sections 125 and 126) were not read. Later amendments were not checked.
