alkaloids come from the resin of opium poppy, Papaver somniferum. Morphine is
attached to the receptors in the brain and spinal cord to block pain signals. Morphine
impacts the level of dopamine and serotonin by acting in the brain's reward system.
Breathing and heart rate are also modified due to morphine which has both short-term
and long-term effects. Morphine can last up to 4 to 6 hours in blood. It also acts on the
