The short answer
Cannabis vaping is not risk-free. Health Canada says cannabis-vape aerosol can contain harmful substances and metals may leach from device components into the extract. Health Canada says vaping is less harmful to lungs than smoking cannabis, but still carries its own risks.

What Health Canada says about aerosol and devices
A vaporizer heats liquid or solid cannabis extract to make an aerosol. Device parts include a battery, heating element, chamber or cartridge, and mouthpiece. Health Canada warns that accessories can malfunction; it also advises using authorized retailers, following the manufacturer's instructions, cleaning the device, and avoiding over-charging rechargeable batteries.
Practical checks, without a safety guarantee
Choose legal cannabis from an authorized Canadian retailer. Legal cannabis products are quality-controlled and tested for harmful contaminant levels. That is a useful product check, not proof that inhaling an aerosol is harmless or that every device is defect-free. Report a device problem or side effect through Health Canada's reporting page. See our Canadian cannabis label guide for package information; labels do not provide an individualized safety assessment.

No. Legal products are quality-tested for harmful contaminant levels, but Health Canada still describes inhalation risks; testing is not a guarantee of zero risk.
What should I check before using a cannabis vape?
Use a legal product and accessory from an authorized retailer, follow the manufacturer's instructions, clean the accessory, avoid over-charging rechargeable batteries, and report a device problem or side effect to Health Canada.
