This condition is caused by impaired thyroid gland function, and results in severely depleted thyroid hormone levels. It can cause coarsening and/or thickening of the Acquired Hypothyroidismhair, cause the skin to dry out, and cause the nails to turn brittle. Other patients also experience extreme inability to handle cold temperatures, unusual fatigue or weakness, depression, and inability to concentrate.

Although marijuana does not actually cure hypothyroidism, it can help ease many of the symptoms of the condition, improving concentration in some and possibly even erasing depression.
