Does nicotine cause veins constrict?

Some of the strongest evidence supporting the medical use of marijuana is marijuana’s benefits for managing chronic pain. Cannabinoid compounds (see "Cannabis 101") interact with receptors in nerve cells to slow down pain impulses and ease discomfort. Cannabinoids also have been shown to be effective in quelling nausea and vomiting. In addition, marijuana is a powerful appetite inducer. The combination of these attributes makes marijuana a therapeutic option for people coping with the side effects of chemotherapy and others who are in danger of unintended weight loss. However, in conditions where gaining extra weight might exacerbate existing health problems, such as diabetes, appetite stimulation would be counterproductive.

Why do my eyes turn red after smoking weed?
Ok so I have heard the reason your eyes get red is because marijuana constricts the blood vessels. Does anyone know which chemical in marijuana does this or if it happens all throughout the body? I was just wondering when someone suffers a large laceration or avulsion (loss of body part), and the first thing you want to do is stop the blood flow and place pressure on the wound to stop the blood from gushing out, well if marijuana constricts blood flow in large doses could it constrict blood vessels enough to have a noticeable reduction in blood flowing from a wound. Would it stop the blood flow enough to create coagulation and speed up the healing process? Just curious if anyone has some input on this I would really like to hear it.
