Understanding The Combined Risks 

Mixing cannabis with alcohol or other drugs can create unpredictable outcomes for both the body and mind. 

Substance Safety 

Experts stress the importance of substance safety. Combining cannabis with alcohol may reduce coordination and slow reaction times, while pairing it with sedatives can heighten fatigue and dizziness. 

Combined Effects Cannabis 

When used together, the combined effects of cannabis and alcohol can be stronger than expected. This may increase the likelihood of accidents or negative side effects.

Patients also face polysubstance use risks if cannabis is mixed with multiple substances. These risks include dependency, confusion, or greater strain on the liver and cardiovascular system. 

In summary, cannabis and alcohol interactions present real concerns, especially for patients managing chronic pain. Avoiding these combinations or seeking medical guidance is the safest approach.
