Why Test for Heavy Metals?
The cannabis industry has a responsibility to provide a safe product to the patients using it. If a grower’s soil or water is contaminated with heavy metals, these toxic elements will be passed into the plant and on to the consumer.
MM Labs testing protocols provide growers, dispensaries, and patients the opportunity to learn if their medicine is contaminated with toxic heavy metals.
MM Labs uses Inductively Coupled Plasma Mass Spectrometry (ICP/MS) to screen samples for metals such as lead (Pb), arsenic (As), cadmium (Cd), and mercury (Hg). This extremely sensitive technique allows you to rest assured that the levels present in your product are at safe levels.
What are Heavy Metals?
The term “heavy metal” can be a little vague as there is no single definition. A common usage today refers to elements in the periodic table with atomic weights greater than 20 and that have a toxicity of concern for humans and the environment. Nevada medical marijuana regulations currently define heavy metals to be arsenic, cadmium, mercury, and lead. Heavy metals are naturally present in water and soil at various levels, and as plants grow, they may absorb and concentrate them. Because heavy metals are everywhere, there is no way to be “heavy metal free” or a 0 level, and so regulations have established generally considered safe levels of heavy metals in products meant to be ingested or inhaled.
