Mental Effects of Methamphetamine
When methamphetamine is used, regardless of method of administration, the drug will eventually reach the central nervous system (CNS). Methamphetamine will not only enter the neurons direct through the neuronal membrane, but will also block the transporters. This therefore makes it impossible for the dopamine neurotransmitters to be transported back into the pre-synaptic neuron and be repackaged into vesicles. This causes an increase in dopamine levels. The use of this drug will eventually lead to the short term effects:
If meth is used too often and for too long, it may lead to a decrease in motor speed, as well as a decrease the ability to learn verbally.
