I've noticed that increasingly more vendors are offering acrylic drip tips. I recently received my first from mad vapes and I love it. I noticed, however, that after cleaning it with isopropyl alcohol it tasted and smelled strange so I googled it and learned that not only can alcohol cause acrylic to break down resulting in fissures and cracks, but there may be some health concerns as well from the interaction between the two. Perhaps our resident chemists can shed further light on this. Since we not only put these in our mouths but inhale vapor through them, I felt uncharacteristically compelled to share with the class.
