According to recent scientific research, indiscriminate marijuana use or marijuana abuse can lead to health problems. It is important to note that the psychological effects of marijuana usage take place almost on an immediate basis after smoking with the highest peak between 30-60 minutes. The effects of marijuana use tend to disappear after 2-4 hours. When eaten, marijuana demonstrates its effects after about 1-2 hours and such effects of marijuana can last for 3-10 hours.
The most important effect of marijuana is the intensification of the emotional state an individual is in, and this effect may vary from one individual to another. It is worthwhile to note that effects of marijuana use depend on the quantity and quality of cannabis taken, personal conditions such as mood, the way to use marijuana (smoked or eaten), and experience of the user. The consumption of marijuana brings a euphoric feeling that slowly changes into a satisfying feeling of relaxation and calmness. Other typical reactions are the desire to eat and consume sweet things such as sugar and sweets & an uncontrollable fit of laughter.
A recent study appearing in the Science magazine suggested that marijuana seems to have a greater effect on thinking and perception than on reflexes and coordination, but only during the usage phase – not after THC has left the bloodstream.
Other scientific studies in the past have suggested that marijuana usage may lead to temporary health complications such as altered time perception, bloodshot eyes, anxiety, difficulty in learning and concentration, nausea, headache, and decreased coordination.
The chronic marijuana use may also include dry mouth, relaxation of the muscles, change in blood pressure, increased heartbeat, and sense of cold or hot hands and feet. However, these effects of marijuana use are temporary in nature and mostly disappear after a couple of hours.
