1. Mary Jane

Print this image onto a sticker and you’ve got an instant costume. It can work with a female or a dude in a dress. Enhance this costume with a green wig, green clothes, green shoelaces, and of course some green nugs to share.

2. The Grim Reefer

You’ll need a hooded cloak, and instead of holding a scythe, you can carry a bong. Paint some pot leaves on your cheeks, and bring the killer chronic.

3. Willie Nelson

Here’s some inspiration showing Willie Nelson’s signature style, incorporating the double braids, cowboy hat, bandanna, guitar, beard, and red-white-and-blue colors.

4. Pothead

(pothead found on grasscity forum)

Wear a pot on your head. You can go with a planted pot (may need to raise the bottom somehow), or an upside-down cooking pot that fits properly.

5. Michael Phelps

How about wearing a boycott Kellogg’s t-shirt, a gold medal around your neck, and wear a swim-cap with the U.S. flag on it. And maybe a speedo if you want to go all out. Here are some more pics of Phelps.

6. Abraham Lincoln

Put on a black suit, a top hat, a beard, and maybe some small stilts for height (he was six feet four inches tall).

Carry an old-fashioned pipe with cannabis in it, as apparently Lincoln was fond of the ganja:

“Two of my favorite things are sitting on my front porch smoking a pipe of sweet hemp, and playing my Hohner harmonica.” – Abraham Lincoln.

(I’ve not verified the original source of the above quote, so make of it what ye shall)

7. A White Widow

If you’re crafty, you can put together a spider costume that is all white. Instead of an hour glass on your belly, go with a green pot leaf. If you count your own legs and arms, you’ll need four extra appendages (the woman in the image has two too many).

8. Dank Doctor

Wear a white lab coat, a stethoscope, and spice it up with a pot leaf tie. Shown above is Dr. Mahmoud ElSohly, who grows marijuana at Ole Miss.

9. Otto Mann From The Simpsons

Otto likes the psychedelic pink, as he decks himself out in a pink t-shirt, pink hat, pink shoes (sometimes black and white shoes), red-foam headphones, blue shorts, long dark hair, a beaded bracelet, and a walkman.
