In the early 1990s, the average THC content in confiscated cannabis samples was roughly 3.7 percent for marijuana and 7.5 percent for sinsemilla (a higher potency marijuana from specially tended female plants). In 2013, it was 9.6 percent for marijuana and 16 percent for sinsemilla.
Parkinson's Disease. For many people with Parkinson's disease, fatigue is just as disabling and unpleasant a symptom as the motor slowing or the trembling. Fatigue undermines all kinds of daily activities and rehabilitation programs. It feeds into our emotional reactions to Parkinson's symptoms and makes them all the harder to bear.
Parkinson's produces many common symptoms, including tremor; muscle rigidity or stiffness of the limbs; gradual loss of spontaneous movement, often leading to decreased mental skill or reaction time, voice changes or decreased facial expression; gradual loss of automatic movement, often leading to decreased blinking, decreased frequency of swallowing, and drooling; a stooped, flexed posture, with bending at the elbows, knees and hips; an unsteady walk or balance; and depression or dementia.
