The Hidden Dangers of Bare-Handed Herb Grinding: Why You Should Use a Grinder Instead

During the preparation of cannabis for use, two main methods are commonly employed: grinding with bare hands and using grinders. However, both of these methods pose hidden health hazards that have not been thoroughly researched. For instance, bare hands grinding can introduce molds and bacteria to the cannabis, as our hands often come into contact with our faces multiple times per hour, transferring facial bacteria to the plant. On the other hand, grinders may be contaminated with heavy metals and plastics, which can defile the cannabis. As a result, patients may unknowingly be exposed to accessories that could potentially pose risks to their health. Despite efforts made by growers to produce clean cannabis, the lack of education and global standards regarding the importance of clean and sterile preparation methods for cannabis medication means that the quality of the medicine can be compromised as soon as it leaves the facility.

 While hand-grinding herbs may provide a tactile experience for some, it is not recommended due to several reasons. Research shows that our phones, which are often used during hand-grinding, are 10 times dirtier than a toilet seat, and our hands can transfer various microorganisms to the herbs, including Demodex mites that can cause contamination and skin conditions. Moreover, hand-grinding can result in loss of potency as delicate trichomes, the resin glands containing medicinal material, can easily be detached from the plant material. In fact, studies have shown that using a grinder can retain up to 30% more trichomes compared to hand grinding. To avoid contamination and loss of potency, it is advisable to use a grinder for herb grinding and avoid using your phone as a surface. Instead, opt for a designated tray or surface that is easy to clean and sanitize

Does it poses danger?

Individuals with weakened immune systems are at a greater risk of falling ill when exposed to parasites and external contaminants. These external contaminants can include not only parasites, but also heavy metals, color pigments, and other similar materials found in our daily lives.

For example, heavy metals such as lead, mercury, and arsenic are commonly found in food, water, and consumer products. Exposure to these metals can cause a range of health problems, including neurological damage, developmental delays, and cancer. Similarly, color pigments used in cosmetics and other consumer products can also be harmful, leading to skin irritation and other adverse reactions.

Citations to back up these claims can be found in numerous studies and articles. For instance, a study published in the International Journal of Environmental Research and Public Health found that exposure to heavy metals such as lead and cadmium can have serious health consequences, including increased risk of cancer and other chronic diseases ( Additionally, research published in the Journal of Toxicology and Environmental Health showed that exposure to certain color pigments can lead to skin irritation and other adverse reactions (
