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 disease (PD) is a long term disorder of the central nervous system that mainly affects the motor system. The symptoms generally come on slowly over time. Early in the disease, the most obvious are shaking, rigidity, slowness of movement, and difficulty with walking. Thinking and behavioral problems may also occur. Dementia becomes common in the advanced stages of the disease. Depression and anxiety are also common occurring in more than a third of people with PD. Other symptoms include sensory, sleep, and emotional problems. The main motor symptoms are collectively called parkinsonism, or a parkinsonian syndrome.
