This purely sativa strain is known as an heirloom in Amsterdam, where it was first grown by Barney’s Farm. Its flavor profile features spicy pepper notes as well as chopped wood and pine trees. Named after Dr. Lester Grinspoon, this strain provides users with a sense of blissful transcendence as well as bursts of energy and positivity. It can also be used to induce creativity for artistic projects and is a good combatant of mood disorders and muscle spasms. The most common side effects of Dr. Grinspoon include dry eyes and a dry mouth, so it may be good to keep water nearby.
