For sure. It says medical grade silicone with no logos.....in the medical and pharmaceutical industry silicone contaminants are a known problem..it doesn't matter how pure or whatever, its completely soluble in the solvents we use. Even in the medical industry we are aware and try not to leech but yea it happens. That's why the silicone tubing will become stiff and will lose its stretchiness...silicone shouldn't be used with butane or really even iso or etoh as its still somewhat miscible..the completely pure cannabinoids aren't much better for direct contact
