Research has shown marijuana use impairs mental functions. Name 3 impairments:
Memory,
Reflexes,
Judgment,
Attention,
Cognitive skills,
Perception.
These impairments can be present while high, but because marijuana stays in the body longer, they can also linger well past the experience of the high. Depending on how much and how often an individual uses, some impairments can be measured even weeks after last use.
