Can you pack Marijuana in checked luggage?

Will TSA arrest me for weed in my bag?

TSA officers do not search for drugs and are not police — but if screening turns it up, protocol is to refer you to local law enforcement. In airports inside prohibition states, that referral is the real risk.

Can I fly with weed within Canada?

Yes, on domestic Canadian flights within the adult public-possession limit — keep liquid or topical cannabis in the 1 L liquids bag. Never depart Canada (or return) with any amount: crossing the Canadian border with cannabis is a criminal offence, medical use included.
