THC-A (tetrahydrocannabinolic acid) is a non-psychoactive cannabinoid found in raw cannabis. When heated, it converts to THC, the compound responsible for the psychoactive effects of cannabis.

Yes, if you burn THC-A, it converts to THC through a process called decarboxylation, which can then produce psychoactive effects and get you high.

The 2018 Farm Bill legalized hemp and its derivatives, including THC-A, provided they contain no more than 0.3% Delta-9 THC by dry weight. Since THC-A is non-psychoactive and not Delta-9 THC, it falls within this legal framework, making it legal under the Farm Bill as long as the product's Delta-9 THC content remains below the specified limit.
