Let them leave and they just keep making them. Create an actual Canadian car company. Just take Jeep and make them actually good and ignore Stellantis trademark, IP, and copyright etc.
You can get a free trial of Tidal and you can probably rent a good quality headset from a big music store for a reasonable price. This would let you check if you can notice a difference.
Also libraries sometimes have awesome gear to borrow if you are near one that is cool. With catching out if it means free
Dosage levels probably vary widely between different places. Composition will change but the important part is the active/medical ingredients, the other stuff is just usually to prevent tampering or to make easier to take. Coated/non coated. Crush resistance or interference, possibly agents to reduce ingestion discomfort etc. how many mg of the active ingredient (acetaminophen is paracetamol) is usually the difference. Cutting pills in half is often just as good as taking a lower dose pill. Just depends on who needs it.
Think the general guideline is not to exceed 4000mg per 24h period ages 12+ though always read the medications guide lines
Oh and ban sales of Stellantis in Canada
