Hello i am relatively new to this forum and cannabis itself. I have been experimenting with different methods of consumption like vaporizing oils and prefilled cartridges, and just recently dry herb vaporizing in a Vap Cap! just recently i started noticing this ear poping feeling about 5 to 10 min after vaporizing its like the feeling you get when going to the mountains or taking off on a plane. Its almost like your hearing is a bit off as well kinda like your under water. I'm wondering if any of you have experienced this? It has happened a few times like within the last week. I'm also looking for peoples opinions on CHS (Cannabinoid Hyperemesis Syndrome) what do you think is causing CHS? I think its possibly from the toxic pesticides used in the grow process. But I'm open to hearing your opinions and experiences with CHS and how you might avoid it?
