You can use marijuana through various modes, but they are dependent on the form of marijuana products and the type of reaction you are after. If you want immediate relief from your symptoms, you better smoke a joint or use a vaporizer. You can also apply patches or cream around the areas you are ailing, and the medicine will be delivered straight into your blood capillaries.
For instance, if you are suffering from a headache, you can apply Critical Mass CBD strain patches on your neck, shoulder, and ears; they help ease the tension and aches around these areas, thus easing the head pain. The good thing about patches is that they last for a few days and release the medicine in intervals; therefore, best if you tend to suffer from headaches often.
If you want the effect to kick in by the time you are getting home from work, you can take pills, oral drops, edibles, or infuse cannabis oils with your food and drinks. These methods are discreet, making them easy for you to use at work.
