People who grow cannabis for the sick perform a truly sacred act. Anyone who chooses to go through the time, the effort, and the risk of growing or legally providing medicinal grade cannabis for these patients ought be respected rather than chastised. And in a day and age in which this medicine is more readily available than ever before, it is important to be able to distinguish between clean and contaminated medicine.
First, visually examine the color of the cannabis. Bright green usually indicates that the flowers are not cured. As cannabis cures, the greens darken and more orange, red, and yellow colors appear.
