What is Heavy Metal Testing?

Heavy metals are toxins which have no use in the manufacturing of pharmaceuticals and other products. The specific heavy metals tested for in marijuana include lead, mercury, cadmium, and arsenic.

During the testing process, three main categories of cannabis get tested namely inhalable cannabis products, inhalable cannabis, and other cannabis and cannabis products.

Heavy metal testing in cannabis carried out by cannabis cultivators on the soil, the water, the nutrient medium, and the cannabis plants for the first time. The second and subsequent times should be when the cultivator changes any part of the growing process. This includes the cannabis strain, the growing media, pesticides, and fertilizers.

Testing requires an Inductively Coupled Plasma Mass Spectrometry (ICP-MS). This is a highly sensitive heavy metal detector that keeps you within the regulations for each state. Most states implementing the heavy metal testing regulation allow only trace amounts of the heavy metals in your weed.

The allowable amounts are as follows:

  • Lead: 0.5 μg/g for both inhalable cannabis and cannabis products, and other cannabis and cannabis products.
  • Mercury: 0.1 μg/g for inhalable cannabis and cannabis products, and 3.0 μg/g for other cannabis and cannabis products.
  • Cadmium: 0.2 μg/g for inhalable cannabis and cannabis products, and 0.5 μg/g for other cannabis and cannabis products.
  • Arsenic: 0.2 μg/g for inhalable cannabis and cannabis products, and 1.5 μg/g for other cannabis and cannabis products.

If you carry out a test and get results above these figures, you know your weed isn’t safe for consumption.

The primary focus of this test is to provide safer cannabis products for consumers. This article gives an in-depth analysis of the issue with the attention being on the effects of the heavy metals on the body.

  • Mercury affects the brain, the thyroid system, and the kidneys.
