cannabis campbell Reviewed by cannabis campbell on . What do you think is the greatest invention ever is? Mine has to be light bulbs by Thomas Edison. Simply because they aid us in every day (and night for the pedants) life. It must of been a bitch to use raw fire every time we needed to see artifically. We take them for granted. Big up Thomas Edison. Rating: 5
