Notwithstanding any other law, any person may purchase, possess, or use tear gas and tear gas weapons for the projection or release of tear gas if the tear gas and tear gas weapons are used solely for self-defense purposes, subject to the following requirements: (a) No person convicted of a felony or any crime involving an assault under the laws of the United States, the State of California, or any other state, government, or country or convicted of misuse of tear gas under subdivision (g) shall purchase, possess, or use tear gas or tear gas weapons.

The contents are dangerous--use with care."

(a) Notwithstanding paragraph (4) of subdivision (a) of Section 12403.7, a minor who has attained the age of 16 years may purchase and possess tear gas or tear gas weapons pursuant to this chapter if he or she is accompanied by a parent or guardian, or has the written consent of his or her parent or guardian. (b) Notwithstanding paragraph (3) of subdivision (a) of Section 12403.7, a person may sell or furnish tear gas or a tear gas weapon to a minor who has attained the age of 16 years and who is accompanied by a parent or guardian, or who presents a statement of consent signed by the minor's parent or guardian.

But read the whole code chapter for other applicable code sections, such as: 12404. Nothing in this chapter authorizes the possession of tear gas or tear gas weapons in any institution described in Section 4574, or within the grounds belonging or adjacent to any such institution, except where authorized by the person in charge of such institution. (back to me, now) Section 4574 covers (as you may have guessed) "any state prison or prison road camp or prison forestry camp, or other prison camp or prison farm or any other place where prisoners of the state prison are located under the custody of prison officials, officers or employees, or any jail or any county road camp in this state, or within the grounds belonging or adjacent to any such institution".

You SHOULD be able to carry around pepper spray to protect yourself,as long as you don't mis-use it,however,I don't know about any LAWS for it,but you can ask your parents to go on a legal website to look up info-Good Luck!*
