Short-term effects of marijuana (for all those people that think smoking marijuana is ok)
Almost immediately after first smoking marijuana the effects begin and may continue as long as two or three hours. A burning sensation in the mouth, a dry throat, bloodshot eyes and increased appetite are common. Also, consistent with brain areas most affected, short-term effects may include impairments in thinking, problem-solving, judgment and comprehension, as well as impaired short-term memory. Time perception is altered and behaviors become limited due to impaired speech, concentration and coordination abilities. Sensory perception becomes distorted in terms of vision, hearing and touch. Physiologically, marijuana lowers blood pressure while increasing heart rate by 20 to 100 percent, which can last up to three hours. This drop in blood pressure, combined with an increased heart rate, is serious because, as the NIDA reports, a person smoking marijuana has four times the risk of experiencing a myocardial infarction (heart attack) within the first hour after inhalation. Moreover, while this substance is known for its euphoric state or sleepiness, it also can produce anxiety, paranoia with hallucinations or panic attacks.
