First Amendment - Religion and Expression. Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. He's right. The first amendment gives him the right to say whatever he pleased. He can say he murdered 500 people if he wants. He can also say if a drug is good or bad in his opinion. Or do we need to make a new amendment for freedom of opinions?
