What can influence whether marijuana acts as a stimulant or depressant?

The level of THC is a crucial factor in determining whether marijuana acts as a stimulant or depressant. THC, or delta-9-tetrahydrocannabinol, is the primary psychoactive compound in cannabis and impacts the central nervous system in various ways. Higher levels of THC tend to produce more pronounced psychological effects, such as euphoria and increased energy, which can be perceived as stimulating. Conversely, lower levels of THC may result in feelings of relaxation and sedation, further leaning towards depressant-like effects. Thus, the overall impact of marijuana can change significantly based on the concentration of THC present in the strain or product consumed.

While other factors, such as the strain of cannabis, method of consumption, and user's age, may also play roles in the experience and effects users report, the concentration of THC is a primary and direct determinant of whether the drug will produce stimulating or depressant effects, making it the most pertinent option in this context.
