Eating raw cannabis will absolutely get you high, and heating it doesn't noticeably affect the potency.
"Decarboxylation" or the removal of a carboxyl group, where it's usually released as CO2, is a common reaction in chemistry, and it doesn't tend to require a lot of activation energy. Every amino acid is decarboxylated after you consume it. Carbonic acid in soda decarboxylates itself at standard atmospheric temperature.
And in the case of your stomach, the HCl will decarboxylate the weed you eat just fine.
Instead of spreading stuff like this, just go and try it. It's really kind of exasperating to read outright fabrications, but when they are this easy to disprove I can't even see a charitable interpretation of why you would do so.

> We report here the case of a young infant with significant accidental inhalational lung injury related to dispersal of mineral dust from an ultrasonic home-use humidifier. The clinical consequences included prolonged hypoxemia, tachypnea, and failure to thrive. Radiography revealed pneumonitis, and pulmonary-function testing showed a nonreversible mild obstructive ventilatory defect.

> These results indicate that aerosol particles released from ultrasonic humidifiers operated with tap water initiated a cellular response but did not cause severe acute inflammation in pulmonary tissue. Additionally, high mineral content tap water is not recommended and de-mineralized water should be recommended in order to exclude any adverse effects.
What gets me is the carrier substance. I think I heard propelyne glycol and vegetable glycerin in the lungs may have metabolic effects. Wonder what alternatives exist or are already being used in medicine now.
