On the other hand, CBD is much safer for memory. According to the World Health Organization (WHO), it has zero risks on one’s health.

Consequently, you could continue imbibing or using it for years without suffering adverse effects. More importantly, CBD is quickly transitioning into a drug that’s worth using in treating different ailments.

Based on the above-mentioned studies, the more THC you consume the higher your chances might be of damaging your short-term memory permanently. Worse, is the fact that the brain’s ability to encode memories can also suffer if you keep using cannabis heavily for a long time.
