To start, your entire argument is fallacious at best.

-Appeal to emotion.
-Trying to use anecdotal evidence as an argument.

There is absolutely nothing in this post or video to support your argument that isn't a fallacy.
I see someone who claims to be the wife of an Alzheimer patient. Where is the patient?
I see her talking about his emotional distress and how the oil helped his depression and anxiety. Which is great.... but not an argument for THC breaking up amyloid plaques. It is, however, an argument for CBD helping with anxiety which HAS been proven as a use for CBD (along with alleviation of nerve pain in cancer and neuralgia patients).

I also hear her call her husband, who is suffering, a pain in the ass. This bothers me greatly since I had to deal with an elderly parent in the late stages their life deal with dementia.

If THC breaks up the amyloid plaques, show SOMETHING that supports your argument. The wife said nothing about how her husbands dementia was improved. Just his quality of life due to the easing of his emotional distress, which is great, but that's not what you're trying to show here.

Also, correlation is not causation. So, you take someone off the medications that are meant to treat Alzheimers and something changes in their demeanor. This could entail any number of things, from the possibility of the patient being misdiagnosed as having Alzheimers when they actually have a completely different form of dementia, if it's dementia at all and not something completely unrelated in a physiological sense like hydrocephalus, to the patient having a negative reaction to that particular medication or combination a meds.

So, to your second question "What do you stand for??":

I'll go with the moniker of libertarian for simplicity's sake. That being said, in regards to cannabis legalization and regulation by the government, I feel like it isn't something the government should be involved in to begin with. However, when you don't want an overbearing state entity to regulate everything in life, there is a need for everyone to do their due diligence, to develop values that are compatible with that way of life in addition to virtuous attributes, such as honesty to one's self and others.

For the interests of keeping this relatively short, because I could probably go on, I'll make this my closing statement... if you believe in pushing for the exploration of cannabis as a treatment for something such as this, you should probably do the work to present a bit of a better argument than what you have presented because all I see right now is a really weak video with no real evidence in an attempt to manipulate people's emotions in order to upvote your post (which they are most likely doing so you either follow them back or upvote their comments) along with a BTC donation address being plopped down in addition to a Patreon link.

Should I keep going, or do you understand why I don't feel obligated to upvote your post nor should I feel obligated to refrain from downvoting it?
