Biochemical Effects
The most prevalent psychoactive substances in
cannabis are cannabinoids, including
delta-9-tetrahydrocannabinol (?9-THC, commonly
called simply THC) and tetrahydrocannabivarin
(THCV),
--Cannabis cofactor compounds -- lowering body
temperature, modulating immune functioning, and
cell protection.
--THC and cannabidiol are also neuroprotective
antioxidants.
--THC and endogenous anandamide additionally
interact with glycine receptors.
13
Biochemical Effects
Biochemical mechanism in the brain --the use of
cannabis affects the brain in the same manner as
a naturally occurring brain chemical.
--The CB1 receptor -- in the brain--mediates the
psychological effects of THC. --The CB2 receptor
-- on cells of the immune system.
--Cannabinoids likely have a role in the brains
control of movement and memory and natural pain
modulation.-- affect pain transmission and
interact with the brains endogenous opioid
system (important pathway for medical treatment
of pain)
14
Short Term Effect
Psychoactive Effect --As the chemical THC
reaches parts of the brain, it attaches to
cannabinoid receptors. --Usually the receptors
are blocked by anandamide produced at low rates
by the body, but the large percent of THC
increases the blocking of the receptors, and
allows dopamine to flow freely. --As dopamine
reaches the receptors, the body experiences a
heightened focus, and a greater level of
perception --resulting in extremely elevated
emotions and feelings.
15
Short Term Effect
Neurological Effect --The areas of the brain
with abundant cannabinoid receptors are
consistent with the behavioral effects produced
by cannabinoids. --Cannabinoids, depending on
the dose, inhibit the transmission of neural
signals through the basal ganglia and cerebellum.
--disruption of short-term memory formation--
Cannabinoids inhibit the release of several
neurotransmitters in the hippocampus --decrease
in neuronal activity in that region
16
The Detriment of Cannabinoid
1)Neurological disorders
Unconsciousness Anxiety Melancholy
2)damage our memory and behavior cause
The function of brain, attention, calculation
ability and sense will decrease or loss.
17
3)Effect the immune system
can damage the body's immune system, resulting
in cellular and humoral immune function,
vulnerable to viruses, bacterial infection
4) Effects of movement coordination
damage muscle movement coordination functions,
resulting in complex standing balance disorders
18
The Benefite of Cannabinoid
Cannabis used medically has several beneficial
effects.
--amelioration of nausea and vomiting
--stimulation of hunger in chemotherapy and AIDS
patients
--lowering eye pressure (for treating glaucoma)
--Painkiller
--Relaxing muscles (for treating multiple
sclerosis)
--treating depression
19
Break the addiction
Setting ones mind at rest.
Taking part in some specific exercises.
Getting professional psychological doctors
help.
Abrupt stop can cause people excited, unrest,
decreased appetite, insomnia, hypothermia and
even shivering, fever, tremor. These symptoms
will disappear in 4 5 days. Rehabilitation
needs a long process.
Taking some medicine, like Methadoni
Hydrochloridum.
