Immediate effects of cannabis

Cannabis is rapidly absorbed and metabolised when smoked, less so when ingested (although this can produce a more intense effect). The immediate effects include a sense of relaxation, increased appetite, mood change, reduced thinking capacity, suspicion and paranoia, and impairment in balance. Cannabis may also cause hallucinations, delusions, agitation and panicky feelings in vulnerable individuals. If you observe a person during or immediately after smoking, you may notice the strong smell, and the smoker may have red eyes and a flushed face.
