Factors Affecting THC Impairment Duration
- Body mass and metabolism: Individuals with a higher body mass or those with a faster metabolism may experience shorter impairment times.
- THC concentration: Higher THC levels in cannabis products lead to more pronounced and longer-lasting impairments.
- Frequency of use: Regular users may build up a tolerance, leading to less impairment than new users.
- Co-ingestion of alcohol or other drugs: Combining THC with alcohol or other substances can exacerbate impairment and extend the duration.
Safe Practices for THC Consumption
- Be aware of your dosage and the concentration of THC in the products you consume.
- Avoid driving or operating heavy machinery for at least 6-8 hours after consuming THC.
- Consider using low-THC or THC-free cannabis products if you plan to drive or engage in other activities requiring coordination and judgment.
