Hi,
It's a plant .. people can be allergic to things like ragweed, so I would assume that anybody can be allergic to it.

Hi, welcome to the forum, smoking of Marijuana is associated with many symptoms of obstructive pulmonary disease (long term): airflow obstruction, chronic cough, bronchitis, and decreased exercise tolerance. You ay be suffering from acute bronchitis secondary to bacterial infection.
Hence, from your history it suggests that you are experiencing airflow obstruction due to hyper reactivity to marijuana. Allergy in the form of angioedema can be possible, which is due to hypersensitivity reaction (type 1). In such cases, subsequent exposure to it can cause complications.
Hence, you need to quit the smoke completely. You need to keep always antihistaminic with you. You also need to rule out other allergens which you are sensitive to.Take care and regards.
