Low to moderate doses: typically produce euphoria, increased sense of well-being and a pleasant state of relaxation. However, some users (especially first time users) can experience anxiety or paranoia. 

High doses: Can cause delusional and bizarre behavior and hallucinations. These reactions occur most frequently in individuals who are under stress, anxious, depressed, have schizophrenia, and are using the more potent types of marijuana.
