How to add "DRAFT" along the left/right margin?

Question

The draftwatermark package emblazons "DRAFT" across a page or pages. The intention appears to be to ruin a document to make it unusable.

\documentclass{article}

\usepackage{draftwatermark}
% \SetWatermarkLightness{0.8}
\SetWatermarkScale{4}

\usepackage{lipsum}
\begin{document}
\lipsum{1-5}
\end{document}

But what if the intention is just to ward against accidental use of a preliminary document by a sleep-deprived individual, without jarring so much or interferring at all with the readability of the text.

Adding "DRAFT" along the left/right margin would do the trick. Is there a package for that?

Update

The selected solution is heavy-handed, because it uses tikz, which interacts poorly with simple \begin\end{verbatim} formatting. ("Package tikz Error: Sorry, some package has redefined the meaning of...").

A lighter solution, one that 1- uses an existing lighter package, and 2- cohabits with many other packages (geometry, perhaps even memoir, ...) without issues, would be nice.

Answer 1

Compile more than 3 times.

\documentclass{article}
\usepackage{lipsum}
\usepackage{background}
\backgroundsetup{
  position=current page.east,
  angle=-90,
  nodeanchor=east,
  vshift=-5mm,
  opacity=1,
  scale=3,
  contents=Draft
}
\begin{document}
  \lipsum
\end{document}

Answer 2

It's easy to patch this command. Here a code

\documentclass{article}

\usepackage{draftwatermark}
%
\makeatletter
\renewcommand\sc@watermark{%
  \setlength{\@tempdimb}{.1\paperwidth}% change here as you need horiz pos
  \setlength{\@tempdimc}{-.5\paperheight}%  change vertical pos
  \put(\strip@pt\@tempdimb,\strip@pt\@tempdimc){%
    \makebox(0,0){\rotatebox{\sc@wm@angle}{%
        \scalebox{\sc@wm@scale}{%
          \expandafter\expandafter\expandafter\textcolor
          \expandafter\sc@wm@colormodel\expandafter{\sc@wm@colorspecs}{%
            \fontsize{\sc@wm@fontsize}{1.2\sc@wm@fontsize}
            \selectfont
            \sc@wm@text}}}}}}
\makeatother
% \SetWatermarkLightness{0.8}
\SetWatermarkScale{4}
\SetWatermarkAngle{90}
\usepackage{lipsum}
\begin{document}
\lipsum[1-5]
\end{document}

Answer 3

Here's something I concocted for another application, though it is at top and bottom, not left and right. However, since your intention is "just to ward against accidental use of a preliminary document by a sleep-deprived individual," it may be sufficient. It can be turned on/off easily, changed, color added, etc. Syntax is \PageStamp[] (default "DRAFT") and \StopPageStamp, along with \def\PageStampColor{}.

Its also set up to use \thispagestyle{\PlainStyle} or \thispagestyle{\EmptyStyle} to handle using the page stamp with or without page numbers.

\documentclass{article}
\usepackage{lipsum,xcolor}
\makeatletter
%%
%% SET UP CODE TO USE PAGE STAMPS AT TOP AND BOTTOM OF PAGE.  DEFAULT
%% STAMP IS "DRAFT", BUT IT CAN BE USED FOR CLASSIFICATION MARKINGS.,
%% TOO.
\def\PageStampFlag{F}
\def\thePageStamp{}
\def\thePageStampTOP{\thePageStamp}
\def\EmptyStyle{empty}
\def\PlainStyle{plain}
\def\PageStampColor{black}

\newcommand{\ps@pagestamp}{
  \renewcommand{\@oddhead}{\sffamily\color{\PageStampColor}%
                           \hfil\textbf{\Large\thePageStampTOP}\hfil}
  \renewcommand{\@evenhead}{\@oddhead}
  \renewcommand{\@evenfoot}{\sffamily\hfil
                            \begin{tabular}{c}
                            \textrm{\thepage}\\
                            \color{\PageStampColor}
                            \textbf{\Large\thePageStamp}
                            \end{tabular}
                            \hfil}
  \renewcommand{\@oddfoot}{\@evenfoot}
}

\newcommand{\ps@emptypagestamp}{
  \renewcommand{\@oddhead}{\sffamily\color{\PageStampColor}%
                             \hfil\textbf{\Large\thePageStampTOP}\hfil}
  \renewcommand{\@evenhead}{\@oddhead}
  \renewcommand{\@evenfoot}{\sffamily\hfil
                            \begin{tabular}{c}
                            ~\\
                            \color{\PageStampColor}
                            \textbf{\Large\thePageStamp}
                            \end{tabular}
                            \hfil}
  \renewcommand{\@oddfoot}{\@evenfoot}
}
\newcommand\PageStamp[1][DRAFT]{
  \def\PageStampFlag{T}
  \def\thePageStamp{#1}
  \def\PlainStyle{pagestamp}
  \def\EmptyStyle{emptypagestamp}
  \pagestyle{\PlainStyle}
}

\newcommand\StopPageStamp[0]{
  \def\PageStampFlag{F}
  \def\PlainStyle{plain}
  \def\EmptyStyle{empty}
  \pagestyle{\PlainStyle}

\makeatother
\begin{document}
