For a 1st time offense possession of marijuana charge, what should I plead?

In Massachusetts, possession of Marijuana under 1 ounce is a civil penalty which carries a fine of $100.00.  If possession is more than 1 ounce, you should contact a lawyer to defend this action. It may be possible, where it is a first offense, to have the matter dismissed on court costs or continued administratively so it does not adversely affect your record.
