I want to add as a precaution, be careful with the thc component.
I was using a combo of cbd and thc that really helped my spasticity, but I would be come tolerant and need to increase the amount over time. In general I found thc makes me a bit anxious, but the pros seemed to be outweighing that negative. It was like caffeine anxiety- a little uncomfortable but not terrible, and the rest of me felt great.
When traveling for a week out of state I went off it and left it at home. When I came back I resumed my former dose, not realizing that the week off had apparently stripped the tolerance I had built. At first nothing happened, but a few hours later I went into a horrible overdose. They say you can't overdose on cannabis, and medically speaking that's true-- you won't kill yourself, but in every other sense of the word I overdosed. I think ALS made it worse because my muscles became trapped in rictus-- completely rigid to the point of intense pain, yet I was powerless to flex or relax them. I could not move at all due to the full body rigidity. My heart felt like it was beating out of my chest, and I was hyperventilating. I was trapped in my head in an utter horroscape of anxiety- the worst terror/anxiety I've ever felt in my life, and it lasted hours. I could not speak. My husband moved me to the bed, laid with me, and tried to soothe me. He had googled thc overdose and read that the hospital cannot do anything, and that that environment will probably make the anxiety and discomfort worse, so he did his best to take care of me until it passed. It took 3 hours before I could move or speak. And days before I truly felt myself again and not an utterly anxious mess.
It traumatized me so badly that I haven't even been able to touch CBD since then (this happened in july), even though I know CBD alone would not cause any of this. Even the smell just sets my heart pounding.
So just be careful with the thc part. It's not just harmless.
