Doctors are not botanists
This is why it's really important that you read those links in proper context, VEJJ, and why no one should immediately assume that that doctor was uneducated by any means.
It's generally the smoking action itself, along with the competition it gives your oxygen supply and the irritating byproducts of combustion, that work in concert to raise BP in some folks, particularly those with a history of high blood pressure or those who lead sedentary lifestyles, eat a lot of salt, or carry extra weight. It also very much depends on the strain you're smoking. The THC and CBD in cannabis, at least some strains of it, can be very helpful with vaso-dilation (meaning it relaxes veins and arteries and helps lower BP) in some people, and we do indeed know that many types of cannabis are helpful in lowering ocular pressure, or glaucoma, but ocular pressure and BP aren't the same thing and aren't affected in identical ways from smoking.
As a rule, most folks who deal with vascular medicine and encounter lots of cannabis smokers find that they do see higher BPs in those patients. If my husband ever gets free of dealing with his vascular patients at the hospital, I'll ask him to officially confirm this. Vaping is a much safer way to use cannabis long-term and get the beneficial effects from the active ingredients while eliminating the oxygen deprivation/combustion irritants that may raise your BP.
You know the phase after smoking where some people feel anxious and jumpy and their heart rate increases? That's what I call the "adrenergic" phase, where it's rather like you've had a slight burst of adrenalin. It happens if you're smoking sativa-leaning strains more than indicas, and it happens anyway after any type of smoke inhalation because your body, veins, lungs and heart are having to work harder to transport oxygen because your normal oxygen intake is competing with smoke. It's during that adrenergic phase that your BP is most elevated. This again depends on how your own body reacts to smoking.
Please, please, please. Everyone remember that links claiming the wonders of cannabis must be read closely and interpreted correctly, ideally with full knowledge of the fact that they usually aren't even discussing whole smoked cannabis but instead isolated active ingredients. You show those to your doctor, who has access to more links to more full and credible studies and sources than you can shake a stick at, and inform her that she's uneducated, and she'll laugh you out of her office. Rightfully so.[SIZE=\"4\"]\"That best portion of a good man\'s life: his little, nameless, unremembered acts of kindness and love.\"[/SIZE]
